MCON 1.2 Plug Housing for Sealed Harness Applications
The TE Connectivity MCON 1-2282337-5 is a 10-position, 2-row plug housing from the MCON 1.2 series, designed for sealed automotive and industrial wire harnesses that demand a reliable, vibration-resistant interconnect. The 4.00 mm pitch gives the terminal spacing needed for the 1.2 mm contact system — the MCON 1.2 terminal mates with this housing using a standard crimp process, and the female socket accepts the male blade or header. The housing carries both Connector Position Assurance (CPA) and Terminal Position Assurance (TPA) features, which together lock the connector pair and confirm each terminal is fully seated before the assembly leaves the harness board. The glass-filled PBT insulation handles the -40°C to 150°C operating range, so this housing is suitable for underhood engine compartments, transmission zones, and industrial cabinets where thermal cycling is routine.
CPA and TPA — What They Add to the Assembly
The Connector Position Assurance (CPA) is a secondary lock that engages after the plug and receptacle are fully mated, preventing the latch from releasing under vibration or cable pull. The Terminal Position Assurance (TPA) is an insert inside the housing that locks each crimped terminal in its cavity — if a terminal is not fully seated, the TPA cannot close, giving a positive assembly check before the harness ships. These two features together mean the 1-2282337-5 is specified for applications where an unlatched connector or a backed-out terminal would cause a field failure: powertrain, braking systems, and safety-critical industrial controls.
Where This Housing Fits in the MCON 1.2 System
The MCON 1.2 system uses a 1.2 mm-wide contact blade and a 4.00 mm pitch between positions — the same pitch repeated in the row spacing. This 10-position plug housing accepts the MCON 1.2 female crimp terminals (sold separately) and mates with the corresponding MCON 1.2 receptacle header or in-line receptacle. The free-hanging, in-line mounting style with a latch holder means it is designed for wire-to-wire or wire-to-device connections inside a harness, not for board mounting.
